During gypsy moth larval development, which color spots appear on the body?

Explanation:
Gypsy moth larvae are identified by a distinctive dorsal spot pattern. They carry five pairs of blue spots and six pairs of red spots along the back as they develop. This combination is a classic, easily recognized marker that helps distinguish gypsy moth caterpillars from other caterpillars in the field, especially in the later instars when the body is larger and easier to inspect. Other color patterns—such as green or yellow spots, or no spots at all—do not match the gypsy moth’s characteristic markings, making the blue-and-red spot pattern the best clue for identification.
